Hi Greg,
I screwed around with this for quite a while (and looked into writing some
XInput code). Eventually I took the lazy man's approach and did the
following:
1) Patched the kernel mousedev.c driver to forward "unknown" buttons as
keyboard events (with high value keycodes) (see attached patch). It's
not very pretty, but then neither is the kernel/X mouse interface in
general -- good lord, what a crufty hack. It will be *very* nice when X
can handle the /dev/input/* devices properly. I've been using it for
months without problems, but please don't get upset if your console
melts...
2) Used the 'hotkeys' program to make those keycodes do useful things.
(Hotkeys seems to become unresponsive sometimes -- killall hotkeys and
restart it. I've never had to do this more than once per session...)
3) Here's the relevant snippet from my hotkeys keyboard.def file:
<!-- Turbomouse upper buttons -->
<userdef keycode="247" command="xmms --pause">xmms pause</userdef>
<userdef keycode="248" command="xmms --rew">xmms rew</userdef>
<userdef keycode="249" command="xmms --fwd">xmms fwd</userdef>
<userdef keycode="250" command="xmms --play">xmms play</userdef>
<userdef keycode="251" command="xvkbd -xsendevent -text \Aw">xevent</userdef>
<userdef keycode="252" command="xvkbd -xsendevent -text \A\[Left]">xevent</userdef>
The xvkbd business allows one to assign keyboard shortcuts to the mouse buttons.
4) I've also found the 'imwheel' software to be very useful with my Expert
Mouse.
Have fun,
-- Brad
